You can have up to three standard @icloud.com aliases on an iCloud Mail account, and iCloud Mail supports up to 500 rules. Aliases are alternate addresses for the same account—not separate inboxes or Apple Accounts. Custom-domain addresses and Hide My Email are separate features with their own requirements and limits.
How many iCloud Mail aliases can you have?
After setting up a primary iCloud Mail address, Apple allows up to three standard @icloud.com aliases. An alias is an alternate address attached to that account. Messages sent to it appear in the primary inbox by default, and you can send and receive alias mail on iCloud.com and on devices where Mail is enabled in iCloud settings. Apple’s alias guide explains the feature and its limits.
An alias does not create another mailbox or a separate Apple Account. Its address cannot be changed, transferred, or converted into a primary address, and it cannot be used to create a separate Apple Account.
Create or manage an alias
- Sign in to iCloud.com and open Mail.
- Open Mail settings, then choose the option to add or manage aliases.
- For a new alias, enter the address text, a label, and the full name shown to recipients. Apple requires the address text to be 3–20 characters.
- Save the alias. You can later edit its label or displayed name in the same settings area; the address itself cannot be edited.
Interface wording can vary. Apple’s directions apply to iCloud.com Mail.

Disable versus delete
In Mail settings on iCloud.com, you can disable an alias temporarily or delete it permanently. Mail sent to an alias while it is disabled—or after it has been deleted—is returned to the sender. If you have three aliases and delete one, Apple requires a seven-day wait before you can create a replacement.
Apple notes a legacy exception: accounts migrated with five MobileMe aliases keep those five, but deleting one does not allow a replacement.

How many rules does iCloud Mail allow?
Apple documents a maximum of 500 rules for iCloud Mail. Rules filter incoming mail or organize messages already received. Each rule has conditions and an action, and rules run in the order displayed. See Apple’s iCloud.com rules guide for the setup details.
To create or change a rule on iCloud.com, open Mail, go to Mail settings, and choose Rules. Give the rule a name, set its conditions and action, then save it. You can edit, delete, and reorder rules. Apple’s iPhone guide also lists actions such as moving, deleting, forwarding, or marking messages as read; on iPhone, the path is Settings > [your name] > iCloud > Mail > iCloud Mail Rules. Labels may vary by software version.

Do custom-domain addresses or Hide My Email use the three-alias limit?
No. They are separate iCloud Mail options, not standard manually chosen @icloud.com aliases, so they do not count toward the three-alias cap.
| Feature | Address type and eligibility | Published limits | Mail behavior |
|---|---|---|---|
| Standard iCloud Mail alias | Manually chosen alternate @icloud.com address for an account with a primary iCloud Mail address. | Up to three aliases; address text must be 3–20 characters. | Incoming mail goes to the primary inbox by default. A disabled or deleted address returns messages to the sender. |
| Custom email domain | Personalized addresses using a domain you own or purchase; an iCloud+ feature subject to regional availability. Requires a primary iCloud Mail address and two-factor authentication; managed accounts are not supported. | Apple’s support article says up to five domains and up to ten personalized addresses per domain. Its setup guide describes three active addresses per person per domain and sharing with up to five other people. These figures describe different contexts, so do not combine them into one account-wide total without checking the current interface. | Uses your chosen domain rather than an @icloud.com alias. An address already used with a different Apple Account cannot be added. |
| Hide My Email | Random, unique addresses generated through iCloud+; a different address-management model from a manually chosen alias. | Not part of the three standard-alias limit. The cited Apple guide does not establish a comparable account-wide cap. | In Mail on iCloud.com, a Hide My Email message can be addressed to one recipient, and replies can use that same random address. |
For custom domains, Apple’s support article and setup guide describe the feature and the limits above. Apple’s Hide My Email guide covers its separate workflow. Availability and interface options can depend on country or region.
